Comparing "benlai" and "yuanlai"

If something was originally a certain way, or "should be" a certain way, the Chinese words used are often 本来 (běnlái) and 原来 (yuánlái). 本来 (běnlái) is usually an adverb while 原来 (yuánlái) could be either and adjective or an adverb. However, they are used in different ways and different circumstances, so this article will help you distinguish when and where to use them.

Situations only using 本来

本来 as an adverb often requires 就 for emphasis

本来 is used when something is common sense. There are certain expectations for the speaker and listener. Since there is no real English equivalent, it is best translated as "it goes without saying." It can also be translated to "supposed to," following it with a certain expectation.


Subj. + 本来 + 就 + 很 / 不 + Adj.

Subj. + 本来 + 就 + 会 / 要 / 得 / 应该 + Verb


  • 生活本来 就 很 不 容易。Life isn't supposed to be very easy.
  • 搬家 本来就 很 麻烦。Moving is supposed to be very troublesome.
  • 照顾 孩子本来 就 是 父母 的 责任。Taking care of children is supposed to be the responsibility of parents.
  • 老师本来就 应该 好好 备课。Teachers are supposed to prepare their lessons well.
  • 美国 人 本来就 会 说 流利 的 英文。Americans are supposed to speak fluent English.

Using 本来是 expresses a change of plans

If something happened unexpectedly later, 本来 is preferred rather than 原来 considering there is a change of the original situation. 本来 means "originally." Since the action has already happened, the pattern 是⋯⋯的 is suggested here. 是 is optional.


Subj. + 本来 + 是 +(不)要 / 会 / 应该 + Verb + 的,但是 / 可是⋯⋯

Using 本来就 to stress the tone

If you've got an opinion to express after stating how it "should be" or "should not be," then 本来就 will help you sound more convincing. The end of the sentence usually has an imperative or rhetorical question that leads to an opinion or suggestion, emphasizing the tone.


Subj. + 本来 + 就 + ⋯⋯


  • 本来 就 够 瘦 了 ,还要 减肥 吗?You are already thin enough and you still want to lose weight?
  • 他 讲 得本来就 不 对,为什么 还 要 我 听 他 的?What he said was wrong all along, so why do you still want me to listen to what he says?

  • 他说话的方式本来就 很 容易 让人 不 舒服,你 别 介意。The way he tends to speak can easily make people uncomfortable, so don't take it personally.

Situations only using 原来

Using 原来 expresses “It turned out”

原来 is more used to emphasize what you accidentally find out or realize in a situation. 原来 means that the unexpected happened. It's similar to "as it turns out⋯⋯" For this usage, "原来" is normally located at the beginning of the sentence.

The most two useful patterns are as follows:


原来 + 是 + [Fact / Truth / Reason / Purpose]

怪不得 + [Observation / Situation],原来 + 是(因为 / 为了 / 想⋯⋯)


  • 原来 是 你 啊!我 刚才 真 没 看 出来。It is you! I didn't recognize you until just now.
  • 原来 是 这 样 啊,那 是 我 做错 了。Oh, that's it. I was doing it wrong all along.

  • 怪不得 总是 对 他 那么 好,原来 你 一直 都 喜欢 他.No wonder you treat him so well. You've had feelings for him the whole time.
